> In Asterisk 11.x I used my i2001 and i2002 phones with rtp_method=1 but in asterisk 12.x there is no incoming voice on my unistim phones unless the partner is also an unistim phone. So I changed to rtp_method=3, which makes calls mutually audible, but RTP streams are somehow asymmetric: tcpdumping on the asterisk server I can see the RTP stream coming
> from the unistim phone but no RTP stream goes from the server towards the phone! I assume that direction is directmedia or something like that. I tried call forwarding too, but it seems to be unable to handle this asymmetric half-direct, half -indirect RTP connection, and audio gets somehow confused and finally ceases to work.
